Brain wiring illuminated using rabies virus.

Scientists at the University of Bonn have harnessed rabies viruses to examine the connectivity of nerve cell transplants. Using a green fluorescent protein, the viruses show where replacement cells engrafted into mouse brains have connected to the host neural network. The approach advances scientists knowledge of the process and their ability to predict and optimize neural transplantation and functional integration into a host nervous system.
